System Responses:

System Responses: Over/Critically Damped

Frequency : psi Phase Angle: amount the output signal (deg or rad) leads or lags the input signal… Z = zeta

System Responses: Example

System Responses: Underdamped

System Responses: Underdamped Decay Ratio = 0.043 Rise Time ~ 1 Settling Time = 5 Overshoot ~ 20.8%
